Tamil to?? om t may concer/1t.' r

Be it known Ithat l, ROY lil. Cocina citizen of the United States, residing at .Grand Rapids, in Ithe county of `Kent and State of Michigan, have invented new and useful Improvements in Locking Devices, ot which the following-.is a. speciiication.`

like position;

rihe present invention 1relates to locking devices, tor connecting and drawing together members of iurniture and the like; and its object is to provide a simple, economically' constructed, readily installed, very etlicient and easily operated device of that character.

rl`his objectis attained by, and the invention Iinds preferable' embodiment in', `the structure hereinafter particularly described in the body .of this specification and illustrated by the accompanying drawings, in which l i Figure 1 is a tace view of my locking device applied to thepost-andv side railv of a',

bedstead, thepost being shown Ain vertical section and the device inlocking position; Figure 2 is a sectional view of the same taken on a vertical plane corresponding to line 2-2 yot Figure 1; l v

Figure 3 is a top planview of the same, the posty and rail of the bedstead being` shown in horizontal section' taken on a plane.

corresponding to line 3-#3 of Figure '1,

vFigure 4 is a top plan view of the device shown in unlocking position;

,Figure 5 is a face view ot the same in Figure 6 is a which the ldevices supporting platev is formed, the lines on which portions thereof are to be bent to form the plate being indicated in dotted lines; and y Figure formed by bending saidwportions.

ln Figuresl, 2 and 3 my device is shown applied to the furniture members 1 `and 2, the former being a bed post and the latter being a side rail of a bedstead, the device serving to detachably connect anddraw together said cess 3 and a keeper fi therein, being a fixed rod extending horizontally across vthe recess as particularly shown in Figures 1 and 3. My device is carried by the other furniture member-the bed rail 2-and is seated in a. horizontally extending recess 5 in the rails inner side,A and comprises a vmetal plate 6 held in said inner portion 11,

tace view of the blank from vthe portions-1G-,

7 is an'end view ot said plate as V -'lever 18' fulcrumed at 19: on avnoutwardly` members. The post 1 has a re-A recess' 5 as by screws 7 ,Ithe plate being 5 snugly `fitted laterally, ig e.,at itstopjalnd bottom edges, between the upperl andk lower sides of said recess, and being thus held `against lateral movement, up or down, by

the yengagement` therewith-'of the said sides c of the recess which thus'reiniorcev the hold,-

ing effect of the screws. A. locking bolt S keeperl e and an outer which are 'oiiset other as shown, andan: inclined from each portion 12 a hooked 4outer end 9 ladapted'to lock- 'ingly `g engage and 'unlockingly release the `portion l0 and 'an` intermediate theV portions y10 and l11. y The v` outer portion 10 ismovable slidably in its longitudinal directionina slidebearing on the plate 6, such bearingbeing formed by bending first outwardly and then toward each other the portions 13, 14 of the blank 15 (Figure 6) from ,which theplate 6 is `formed.` Y'Vhen the bolt-is Vmoved outwardly from its I locking position seenl in Figures 1 and 3, its outer portionv 10. slides longitudinally in said bearingggand' as the ,outward movement 'of the *bolt continues, its inclined inter-v mediate portion l12y passesinto this bearing, `thereby moving the bolt longitudinally and upwardly-laterally into` its position seen in Figure 5 whereingthe keeper is released. The opposite movement of the bolt,w ot

course, causes the bolt to lockingly engage the keeper and to drawthe members V1 `and 2 tightly'together." A bearingis provided also fortlfi'efinner portion 11 of the bolt in which it moves longitudinally, suchibearing being 17 yof the plate 6, to form which bearing said `portions voit 4the blank 15 are bent as indicated inl Figures 6 and7.

into 'unlocking and 'locking positions byf a The boltJ is moved outwardly and inwardly -I extending tulcrum-carrying,portion 2O 'of the plate, such portion being bent as indicated in Figures 6 and 7. A link 21, pivoted at 22 to said lever and at 23 to an outwardly bent portion 24 oi: the bolt, serves to transmit locking and unlocking movement trom the lever to the bolt. The lever has an upwardly. bent handle 25.

lt willbe seen that my device may be very economically manufactured from died down movement by the sides of the recess 5; and that the device easily operated to connect and draw together the members l and 2, and oppositely to disconnect them.

Dowels 26 are desirably provided, carried by one member (as 2) and removably seated in sockets 27 in the other member (as l) The invention being intended. to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings or hereinbe'fore described.

l claim:

l.` ln combination With a first member having a keeper and a second member, a device of the character described comprise ing; a bolt movable part Way longitudinally and' another part Way longitudinally and laterally in a bearing on the second member into and out of locking engagement with the keeper.

2. ln combination with a first member having a keeper' and a second member, a device of the character described comprising; a bolt; a plate carried by the second member and having a'bearing inwvhich the bolt is movable part Way longitudinally kand another part vvay ylongitudinally and laterally into and out of locking engagement With the keeper; a lever ulcrnmed on the second member; a link pivoted on the lever and on the bolt for moving the bolt.

3, lnfcombination With a first member having a keeper anda second member, a device of the character described comprising; a bolt movable into and out of locking engagement with the keeper and having outer and inner laterally-offset portions and an inclined intermediate portion; a plate carried by the second member and having a bearing in Which at least one of the offset l portions is in a portion of the bolts movement longitudinally slidable and in which bearing the inclined 'portion is slid-able in 'another portion ot the bolts movement; a

lever ulcrumed on the second member; a link pivoted on the lever and on the bolt for y moving the bolt.

t. In combinationv with a first member "having a keeper'and a second member; a

device` of the character described comprislng; a bolt' movable lnto and out of locking naaaeee the inclined portion is slidable in another portion of the bolts movement, and having also` a bearing 1n which the vother offset portion is slldable; a lever tulcrumed on the .second member; a link pivoted on the lever and on the bolt for moving the bolt.

5. In combination `with a first member having a keeper and a second member having a recess, a device or" the character described comprising; a bolt; a plate seated in and held against lateral movement by the second memberg recess and: having a bearing in Which the bolt is movable part Way longitudinally and another partV Way longitudinally and laterally into and out et locking engagement with the keeper; a lever tulcrumed on the second member; a link pivoted on the lever and on the bolt for moving the bolt.

6. In combination With a lirst member' having a keeper and a second member, a

device of the character described compris--` ing; a bolt movable into and ont oi locking engagement With the keeper and having outer and inner laterally-olset portions and an inclined intermediate portion; a plate carried by the second member andhaving n:i tnlcrinn-carrying portion and a bearing in which one et the offset portions is in a portion oit the bolts movement longitudr nally slidable and in Which bearing the inclined portion is slidable in another portion of the bolts movement, and having also a bearing inwhich the other oset portion is slidable, said ulcrum-carrying portion and said bearings being formed by Ybending edges ofthe plate; a lever inly crumed on said iulcrum-carrying portion; a link pivoted on the lever and on the bolt for moving the bolt.

ln testimony whereof l have hereunto set my hand at Grand Rapids, Michigan, this 12th day ot August, 1921.
